Luis bought stock at $50.70. The next day, the price increased $17.75. This new price changed by -3-%

the following day. What was the final stock price, rounded to the nearest cent? Is your answer reasonable?
Complete the explanation.
Answer:
Starting price is $50.70.
Next day the price is $50.70 + $17.75 = $68.45
This price then changed by: [tex]-3\frac{3}{4}\%=-3.75\%[/tex].
So in order to calculate that we do: [tex]68.45 - (3.75/100*68.45)=65.883125 =\$65.88[/tex]
Therefore final price is $65.88.
Yes, this is reasonable.

Write a polynomial function that has a leading coefficient of 1, and the given zeros
at 3, 5, and -i.
9514 1400 393
Answer:
p(x) = x^4 -8x^3 +16x^2 -8x +15
Step-by-step explanation:
Assuming you want real coefficients, the imaginary root means its conjugate is also a root. In factored form, the polynomial is ...
p(x) = (x -3)(x -5)(x -i)(x +i) = (x^2 -8x +15)(x^2 +1)
p(x) = x^4 -8x^3 +16x^2 -8x +15

The incorrect statement for the given condition is;
⇒ |a| > b
What is Number line?
Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
A number line shows 'a' to the left of 0 and 'b' to the right of 0. Point a is closer to 0 than point b.
Now,
Since, Point a is closer to 0 than point b.
And, Number 'a' to the left of 0 and 'b' to the right of 0.
Hence,
Let the number 'a' = - 1
Then, The number 'b' = 2
So, We get;
|a| = |-1| = 1
And, |b| = 2
Clearly, |a| < b
Thus, The incorrect statement for the given condition is;
⇒ |a| > b

The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line is y = (-1/2)x + 7
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Let the equation of the line is y = m(1)x + c
The line is perpendicular to 2x - 8y = 3
The means,
2x - 8y = 3
-8y = 3 - 2x
y = -(3 - 2x)
y = -3 + 2x
y = 2x - 3
This is in the form of y = m(2)x + c
m(2) = 2 and c = -3
Now,
The line y = m(1) + c is perpendicular to y = m(2) + c
So,
m(1) x m(2) = -1
m(1) = -1/2
Now,
The line contains (-8, 11) = (x, y).
This means,
y = m(1)x + c
11 = (-1/2) x -8 + c
11 = 4 + c
c = 11 - 4
c = 7
Now,
The equation of the line is y = (-1/2)x + 7
Thus,
The equation of the line is y = (-1/2)x + 7

The time needed to complete a job is normally distributed with a mean of 1 hour and standard deviation of 10 minutes. Probability to complete the job in hone hour or more, but less than 70 minutes is:
Answer:
The value is [tex]P(60 < X < 70) = 0.34134[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 1 \ hour = 60 \ minutes[/tex]
The standard deviation is [tex]\sigma = 10 \ minutes[/tex]
Generally the 1 hour is equivalent to 60 minutes
Generally the probability to complete the job in one hour or more, but less than 70 minutes is mathematically represented as
[tex]P(60 < X < 70) = P(\frac{60 - 60 }{10 } < \frac{X - \mu}{\sigma } < \frac{70 - 60 }{10 } )[/tex]
=> [tex]P(60 < X < 70) = P(0 < \frac{X - \mu}{\sigma } < 1 )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(60 < X < 70) = P(0 <Z < 1 )[/tex]
=> [tex]P(60 < X < 70) = P(Z < 1) - P(Z < 0 )[/tex]
From the z table (Z < 1) and (Z < 0 ) is
[tex]P(Z < 1) = 0.84134[/tex]
and
[tex]P(Z < 0 ) = 0.5[/tex]
=> [tex]P(60 < X < 70) = 0.84134 - 0.5[/tex]
=> [tex]P(60 < X < 70) = 0.34134[/tex]

Answer:
A quadratic equation has solutions when the graph crosses the x-axis. There are two ways the graph can have no solution, when the "a" value is greater than 0 and is translated vertically above the x-axis, or if the opposite occurs, when the "a" value is negative and is translated vertically below the x-axis.

Adrian's gerbil weighed 68.59 grams at the beginning of the summer. During the summer, the gerbil gained 24.6 grams.
Estimate the weight of the gerbil at the end of the summer by rounding each value to the nearest whole number.
Answer:
94 grams
Step-by-step explanation:
Adrian gerbil weighed 68.59 grand at the beginning of the summer
During the summer the gerbil gained 24.6 grams
Therefore the weight of the gerbil at the end of the summer can be calculated as follows
= 69 + 25
= 94 grams
Therefore the weight of the gerbil at the end of the summer is 94 grams
